AgNO2-mediated cleavage of the N–N bond of sulfonylhydrazones and oxygen transfer: access to fulleroisoxazolines via radical cyclization with [60]fullerene
Reaction of [60]fullerene with α-alkoxyl/phenolyl/acyloxyl ketoxime in the presence of sodium carbonate afforded fulleroisoxazoline or fullerooxazine derivatives via C–C or C–O bond cleavage respectively. O2 was proved to be essential to the reaction.

AgNO<sub>2</sub>-mediated cleavage of the N–N bond of sulfonylhydrazones and oxygen transfer: access to fulleroisoxazolines via radical cyclization with [60]fullerene
The first example involving cleavage of the N–N bond of sulfonylhydrazones is presented, and a new methodology for the synthesis of fulleroisoxazolines is developed.
